Abstract: 1532218 Acoustic holography NATIONAL RESEARCH DEVELOPMENT CORP 23 June 1976 [26 June 1975] 27189/75 À Heading G1G Acoustic holography apparatus comprises an acoustic transmitter transducer 1 for insonifying an object 3, an acoustic receiver transducer 4 or an array of such transducers for detecting acoustic signals from the transmitter 1 which have passed by or through the object or have been diffracted or reflected therefrom, scanning means for producing a displacement of the receiver 4 relative to the object or for selecting signals from each of the transducers of the array in sequence, sampling means for taking samples of a signal derived from the receiver 4 at phase times relative to the phase of the acoustic waves of the transmitter 1, said phase times being selected according to a prescribed relationship with the instantaneous position of the receiver 4, and plotting means 8 for plotting the samples versus the displacement of the receiver 4 so as to form a diagram representing an acoustic hologram of the object 3. As shown, the output signal B cos (#t + # 1 ) of the receiver is applied to a phase-locked frequency multiplier 10 whose output B cos k 1  (#t + # 1 ) is applied to a sampling gate 11. A scan control unit 12 controls the scanning means (not shown) and also applies pulses at the appropriate instants to the sampling gate 11. These instants occur when the phase of the transmitted signal A cos #t reaches a value - # 2  which is dependent upon the instantaneous position of the receiver 4. The signal A cos #t is compared at 13 with the output of a switched potential divider 14 under the control of the scan control unit 12. When the two input signals of the comparator 13 are equal, the output of comparator 13 changes and a pulse is applied to the sampling gate 11. During this pulse, the output of the phase multiplier 15 is applied to an integrator 15 whose output B cos k 1  (# 1  - # 2 ) is applied to the X-Y plotter 8 together with signals from the scan control unit 12. Details of the circuitry of Fig. 2 are described with reference to Fig. 7 (not shown), and the theory and operation are described with reference to Figs. 3-6 (not shown).
